newbie to allotments HELP!

We have just been allocated an allotment 5 poles only as there is great demand for these plots. It is over grown and has lots of bramble roots. they have said they will plough then rotivate ,is this a good idea? or should be do it the hard way digging then putting it in a pile to break down. Any other advice about turning my allotment into something productive would be great.  thanks for the advice in advance

i as Salmo says let them do it, Bramble is pretty easy to clear as the roots are shallow and don't go deep, it's what else is in there that might prove a problem but at least you have a few months weather permitting to get the worst bit over.
